NUT-LOCK.

Specification 01 Letters ratent. Patented Ailg. 15, 1911 Applicationfiled October 21, 1910; Serial No. 588,293,

To all whom it may concern:

Be it known thatI, IRVING (J. WVooDwARn, a citizen of the United Statesof America, and a resident of Chicago, county'of Cook, State ofIllinois, have invented certain new and useful Improvements inNut-Locks, of which the following is a specification,

The main objects of this invention are to provide a simple, efficient,and'inexpensive form of nut lock:

An illustrative embodiment of this invention is shown in theaccompanying drawings, in which-e,

' Figure 1 shows a nut and bolt locked by a nut lock constructedaccording to'this in-' vcntion. F ig. 2-is a section of the same takenon the lineAe-A ofFig. 1. Fig. 3 is a'plan view of the blank beforebeing bent. Fig. 4 is a front elevation of the finished nut lockvshowing the eccentricity of the apertures. Fig. 5 is a section of thesame taken on the line B-B of Fig. 4. I

'In the form shown in the drawings the nut lock comprises a fiatpie'ceof resilient metal 1 b'ent upon itself to substantially U shape soas to form' a pair of legs 2 and 3 extending in the same genera-ldirection and connected together by an inclined back or yoke 4.Apertures 5 and-6 are punched in the blank so that, when the piece ofmetal is bent to theshape shown in the drawings, they will beeccentricallyf located with respect to each otherand their centers liein a line i lined tothe-zlegs in the samegeneral direction as theinclination of the back. These apertures are unthreaded and arepreferably oblong or elliptical, the major mean between the..outside androot diameters being greater than the outside (1i ameter-of the bolt." I

The size of the apertures relative location allows the edgeof eachaperture to be seated in the thread grooves 7 for a short distance onlyas at8 and 9 re spectively. On account of the eccentricity of theapertures thelegs ofthelock enga e respectively opposite sides .of' thebot.

.When in position on the bolt the adjacent leg 2 ofthe lock comes up.fiush against-"the" face of the nut 10 and the back 4; is inclined--away from the bolt and from the face off: the nut.

fingers up to the nut 10 and then it may-be set up with a wrench therebywedg ng the edge of the aperture at 5 between the thread 5 and 6 andtheir The nut lock may be screwed on with the and the face of the nut10. For all ordin ary uses the setting up 'of the nut lock with thewrench will, on account'of the incidental' springing together ofthe-legs of the lock, secure themitlO against removal until the nut lockhas first been removed. However, it' may in some instances as with smallbolts where the resiliency of the nut lock is reduced to a minimum dueto its'size, be desirable to cause a more secure seating of the parts 8and 9 in the thread grooves 7. This can be accomplished by striking ablow with a hammer at- 8 which, on account of the inclination of theback, will tend to increase the eccentricity of the apertures andthereby increase the grip of the nut lock on the bolt.

Although but one specificembodiment of th s invention has been hereinshown, it will be understood that numerous details of the constructionshown may be alteredor omit this invention.

I claim l. A nut lock, com rising a piece of metal bent upon itself toorni a pair of legs ex tending in the same, general direction and havingeccentrically' locatedapertures therein. i i

2, A nut lock, comprising a fiat piece of metal bent upon itself to forma'pa'ir of legs ted without departing from the spirit of extending inthe same general direction,

each of said legs having an aperture therein, said apertures beingeccentrically located relatively to each other.

A nut lock, comprising a flat piece of metal bentgupon itself to form apair of legs extending: in the same general direction,

each of said legshaving an aperture therein,

said apertures being oblong and eccentrically located relativelyrof eachother.

i. A nut lock com rising a flatv piece ,of metal bent upon itsel to'forma pair of legs extending in the same general directi0n,

each ofsaid le gs having. an aperture therein, rsaid apertures beingoblong and eccentrically located relatively of each other in thedirection 0 ,their shorter diametfi is.

5. A nut. lock, comprising affiatpiece of metal, having therein apair'of apertures 'spaced apart and being bent upon itself be tween saidapertures toform a pair of 'legs extending in the same general directionand connected by a back inclined atan angle to .said generaldirection,the inclination of Sflld bfiCk being such as to make the "aper- .turesin said legs eccentric to each other."

6. A nut lock, comprising a piece of metal having therein a pair ofapertures spaced apart and being bent upon itself to form a pairof'le'gs extending in the same eneral direction and having eccentricallyocated apertures therein, and a back inclined at an acute angle to oneof said legs.

7. A nut lock,'compris1ng a piece of metal bent upon itself to form apair of legs extending in the same general direction and havingeccentrically located apertures therein, and a back connecting said legsand inclined thereto in the general direction of the slime of centers ofsaid eccentric apertures. l

8. The combination with a bolt and nut, of a nut lock comprising a flatpiece of metal bent upon itself to form a air of legs extending in thesame general 'directiom eachof said legs having an aperture therein, the

edge of one of said apertures. being adapted to engage the threads ofthe bolt at a point circumferentially spaced away from the point ofengagement of the edge of said point of engagement of the edge of saidother a erture with said threads.

10. e combination with a bolt and nut, of a nut lock com rising a; flatpiece of metal bent upon itself to-form a pair oflegs extending in thesame general direction,

each of said legs having an unthreaded aperture therein, theedge of oneof said aperturesbeing ada'ptedto engage the threads of the bolt at apoint circumferentially spaced away from the point of engagement of theedge of said other aperture with said threads.

1 11;. The combination with a bolt and nut, of a "nut lock' comprising afiatpiece of metal bent upon itself to form a pair of legs extending in:the same general direction,

each of said legs having an aperture therein, said apertures being of adiameter not less than the mean between the outside and root diameters,of the bolt, the edges of said apertures being adaptedto be seated inthe thread grooves at points spaced apart circumferentially, 5 i

12. The combination with a nut and bolt of a nut look comprising a flatpiece of metal bent upon itself to form a pair of legs extending in thesame general direction, each of said legs having an oblong aperturetherein, the major, diameter of said aperture being not less than theoutside diameter of said bolt, and the minor diameter being not lessthan the mean between the outside and root diameters of said bolt, theedges of said apertures being adapted to becomeiseated .in the threadgrooves at points substan: tially diametrically opposite.
